<h2>DESCRIPTION</h2>

<em>r.out.png</em> exports a GRASS GIS raster map in non-georeferenced
Portable Network Graphics (PNG) image format, respecting the current
region resolution and bounds.

<p>
Optionally the user can choose to export a World File (.wld) to provide basic
georeferencing support. When used with the transparency flag this can
create images useful for KML, TMS, or WMS overlays. (e.g. for use in
Google Earth or as OpenLayers tiles) If output is redirected to stdout,
the world file will be called <tt>png_map.wld</tt>.


<h2>EXAMPLE</h2>

The example is based on the North Carolina sample data location.
<p>
Export of the soil map to PNG format with world file:

<div class="code"><pre>
g.region raster=soils_Kfactor -p
# export PNG file with additional world file
r.out.png input=soils_Kfactor output=soils_Kfactor -w
# verify
gdalinfo soils_Kfactor.png
</pre></div>
